Pressure drop in a packed bed with a liquid of variable viscosity: The case of dextrin hydrolysis by immobilized glucoamylase

The activity of an immobilized enzyme in a packed bed is monitored for the change in a substrate conversion with time. But pressure drop in the packed bed with immobilized glucoamylase can serve as an indirect indicator for the changes in the conversion and activity of the immobilized enzyme. The method is simple and the change can be monitored continuously. This method can be generally applicable to systems where the viscosity of a substrate changes with its conversion.
